It can substitute.So carrying out one preferable means when greenfeed in the breeding process, and acid is produced during green storage
Property substance, can promote digestion and absorption of the domestic animal to feed, while under identical volume, the storage capacity of greenfeed is hay
2.5 times.1 cubic metre of greenfeed weight is about 450-700 kilograms, contains 150 kilograms of dry matter, and the hay of same capacity is only
70 kilograms, containing about 60 kilograms of dry matter, it is intended to the method in order to be stored up using forage grass blueness in order to which domestic animal preferably cultivates.
The green storage of herbage refers to for fresh herbage being placed under anaerobic environment through everfermentation, and a kind of succulence, storage endurance is made
, the process of the feed utilized for a long time for domestic animal.Currently, the use of more green storage technology being all that part material is carried out powder
Storage is carried out after broken to cultivate as greenfeed, but existing green storing raw material is single, nutritive value is single, storage time
Short, blueness storage quality ambiguity is higher, when taking greenfeed in use, be easy to contact due to feed with air cause it is secondary
Fermentation causes and situations such as current prior art existence condition is not easy to control.
For these reasons and the deficiencies in the prior art, the present invention provides a kind of methods of forage grass blueness storage, to be sought
The feeding higher longer greenfeed of storage time of value.
Summary of the invention
It is an object of the invention to: in order to solve the storage of forage grass blueness, storage time is short and the feeding quality of the green storage of forage grass is unstable
Fixed, the present invention provides a kind of method of forage grass blueness storage.
The present invention specifically uses following technical scheme to achieve the goals above:
A kind of method of forage grass blueness storage, which is characterized in that including the following steps:
(1) preparation of green storage equipment: selection high-land, drying, the hard draining of soil property well dig ground close to the position of animal house
Cellar, every cubic metre can load material 225-325kg, and before filling cellar, cellar bottom spreads the stalk of 10-15cm thickness, cellar surrounding paving
Plastic film, so that the fully wrapped around drainage trenching around surrounding, cellar of plastic film, being unable to cellar during storage cannot
Leak, surrounding's drainage trenching of cellar prevent from leading to ponding due to heavy rain etc., so that green storage is rotten.
(2) feedstock processing: it is 2-5cm that the fresh feed of harvesting, which is cut into length, by the fresh feed after the completion of cutting
Moisture regulation is carried out, so that the feed moisture content after cutting is 60%-70%, is dried raw material when moisture is higher than 70%
Or the hay that incorporation crushes, the higher fresh feed of moisture content is added when moisture is lower than 60% and is mixed.Moisture content mistake
Raw material is easy compacting agglomeration if height, is lost conducive to the movable of Miyarisan while after plant cell juice can be made to be squeezed, makes nutrient
Damage can make be compacted when green store up if moisture is too low to cause aerobic bacterium mass propagation, make blueness so that there are air is more
Store up mouldy corruption.
